The banking industry is subject to a wave of consolidation taking the form of mergers but also the formation of strategic partnerships. In this chapter, we present how such a partnership can be assessed using the e3value ontology. This ontology allows us to model networks of enterprises and partnerships, exchanging things of economic with each other. To adequately model strategic partnerships, the e3value ontology has been extended to represent investment arrangements and outsourcing constructs. All this is explained using an industry-strength case banking study.
